I still expect Siacoin to be having positive correlations again soon. There recently have been wallet connection errors with some of the exchanges, hence prices have been down lately. However, Siacoin is still expected to have these issues resolved and expected to have updated to their protocol and cloud infrastructure by mid 2018. This makes me believe that a long HODL is called for. This is especially true given that the crypto was still in the top 20 before and has an over 100 million dollar daily trading volume .
